' Specification of Letters Patent.

Patented Jan. 31, rear.

' had to the accompanying drawings, forming part ofthis specification, in which Figure 1 is a sectional side, elevation showing one form of our invention; Fig. 2 1s a cross section on the line 11-11 of Fig. 1;

Figs. 3 and 4: are views similar to Figs 1 and 2, showing a modified form of the 1nvention; and Fig. 5 is another view similar mFig. 3, showing a further and simpler form of the invention.

Our invention relates to the class of turbines, and particularly those intended for driving tools or removing scale or sediment from the interior of tubes.

The object of the invention is to provide a simple and eficient, and long-lived turbine device in which the shocks upon the cutting head are largely absorbed or cushioned before they reach the turbine wheel.

In the drawings, referring to the form of Figs. 1 and 2, 2 is the casing or barrel of the turbine, which is provided with inwardly projecting webs or ribs 3 and l, supportingatubular bearing 5. The webs preferably extend longitudinally for a part of the length of the barrel from the front end, and within the bearing is carried the removable bushing 65, through which the turbine shaft 7 extends. We preferably form at least one of t-hewebswith an oil cavity 8 having holes 9- leading through the removable bushing to the shaft. This bushing may be held against rotation by the screw 10 inserted through the solid web and enter ing the bushing, or the bushing may be pressed in. The oil cavity may be filled through a hole. in a plug 11 which is normally closed by the spring-pressed plug valve 12. The nozzle coupling or rear supply chamber 13 is preferably screwed into the rear end of the barrel or casing, and against the stationary turbine member 14, which has a smooth outer surface fitting neatly against a shoulder 15 in the barrel. The removable nozzle thus serves to clamp the stationary turbine member in place. The

I stationary turbine member has a rear annu- "lar extension 16 of smaller diameter than the bore of the chamber 13, and this is closed by the screw cap 16. The rear reduced portion 17 of the turbine shaft extends back within this chamber, which contains washers 18'and 19 surrounding the shaft and preferably held by a nut and lock-nut 20 and 21. At the front of the stationary turbine portion a Washer 22 seats in a recess therein, and .a ring 23 seats within a mating recess in the turbine wheel 24, a washer 25 being placed between them. A thrust bearing is thus provided for the shaft on both the shaft, though it may be secured in any desirable manner.

In Figs. 3 and 4 we show a form similar to that of Figs. 1 and 2, except that the closure at the rear end of the casing is of different form. In this case the screw coua central hub 26 containing the chamber 27 for the rear bearing of the reduced portion 17 of the turbine shaft. portion is carried on radial webs 28 and 29, which allow the water entering the rear end chamber to flow around the hub to the ports in the stationary part of the turbine. The chamber 27 in this case is an oil chamber having a supply channel with an entrance plug 30 closed by spring-pressed plug 31. Inthis case again the shaft is extended through the stationary member, thrust bearings being provided both at the front and rear of said stationary member. In this case the removable nozzle does not seat against the edge of the stationary member, but clamps it through the bushing 32, against which the hollow chamber 27 abuts.

In Fig. 5, a still simpler form of the invention is shown, wherein the stationary turbine member 14 is screwed into the rear end of the barrel 2 and against the shoulder 15". In this case the nozzle 13 is substantially the same as in the form of Fig. 1, and screws against the stationary turbine member. This stationary member 14' is in this case provided with a rear hub extension 16", which is shown as having an itegral closure with a squared portion 33 for screwing it to place. Within the recess in this sides of the stationary turbine portion. We have shown the turbine wheel as screwed to.

pling 13 is made in the form of a plug with This central hub stationary member are a metal collar 34: and a metal disk 85, to receive the reduced pore tion 17; of the turbine shaft. In tlllST case the bushing 6 has an enlarged rear end porf turbine wheel, which cushions the jarsand shocks, thus savingwear on the turbine. The" extending of the shaft" vwithin or through the stationary member and the pro viding of bearings in front of and in the rear of the turbine wheel, gives a strong and efficient bearing construction, especially in connection with the long outbored bearings The oiling device affords a steady supply of lubricant to the long shaft bearing, and the device is well adapted for the hard usage to which such cleaners are subjected.

Many variations may be made in the form and arrangement .of the parts without departing from our invention.
